Why don't you clean up the spare tranny and pop it in? Its not that much work - is it? Yours is a 23 spline - correct?

Mark, because I would really like to find the reason mine is making this noise- there's not a whole lot to these transmissions and I'm still scratching my head.
I'm one of those people that need to know what happened,lol!
I showed it to Dan @ Brewers over the weekend: aside from the cluster washers being junk and the ends of the cluster gear needing machined, it all looks good.
He said there was some debris that has gone through it.
I'm sure this is a result of the shift fork breaking a year or so after I rebuilt it.
I'm gonna pull the scattershield and see if maybe a spring broke on the clutch disc.
